WD Purple Pro HDD Spec and Price in Italy

SATA12TB7200 RPM

Purple Pro is the enterprise surveillance drive: 7200rpm at every capacity, a 512MB cache, and a five-year warranty with a 550TB/year workload rating — WD's top-end camera-array spec, per the product brief. Where the base Purple handles a few streams, Purple Pro is rated for AI-capable NVRs and large camera counts, with sustained throughput up to 267 MB/s. The distinction from the base line is endurance and warranty, and the price difference tracks it.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Made for surveillance and broadly comparable to the top pick, with twice the cache at the same capacity.
  • Shares much of the design and feature set of the enterprise line.
  • Owners deploying them in surveillance and NVR systems report reliable, trouble-free operation.
  • Owners consider them good value for the capacity, citing capacity and speed.
  • Packaging and shipping are repeatedly praised.

Commonly criticised

  • Loses out to a rival with an included data-recovery plan, and has a lower sustained transfer rate than the enterprise drive it shares characteristics with.
  • Several owners find the drive loud while writing, noisier than the drives it replaced.
  • One owner reports a unit that damaged a motherboard and had to go through warranty replacement.
